Question

sin^2 theta + 1/(1+tan^2 theta)=1
Prove the identity.​

Answer 1

Answer:

hope it helps you dude

Step-by-step explanation:

Explanation:

LHS= 11 − sin 2 x

⇒ 1 cos 2 x

, using identity cos 2 x + sin 2 x= 1

⇒ sec 2 x

, as cos x = 1 sec x ⇒ 1 + tan 2x

using identity

1 + tan 2x= sec 2x

hence=RHS
